Can you help me with this plz

Explanation:

First we need to find the slope of this given line.

The two points on here are (0,-3) and (3,0)

Apply the slope formula

m = (y2-y1)/(x2 - x1)

m = (0-(-3))/(3-0)

m = (0+3)/(3-0)

m = 3/3

m = 1

The slope of the given line is 1. The negative reciprocal of this is -1, which is the perpendicular slope.

Side Note: Any two perpendicular lines always have their slope multiply to -1, as long as neither line is vertical.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
